The Essences of Nanotechnology and its Role in Molecular Nanoelectronics & Communication
Abstract: In this paper, the essence of nanotechnology is reviewed. Most of the properties of nanomaterials and structures arising from the synthesis and growth conditions and physical theory are reviewed. Hence, some of the techniques of synthesizing nanomaterials and theoretical methods used to describe the physical and bio – chemical properties are highlighted. The theoretical formalism is intended to describe the interactions of spins and electrons in atomic scale. The consensus …

Review on UV – Visible Spectroscopy and HPLC
Abstract: Like Fourier-transform infrared spectroscopy, UV-visible spectroscopy is used to determine the purity of pharmaceutical compounds. Many substances have chromospheres, which absorb certain wavelengths of ultraviolet or visible light. Using the Beer–Lambert equation, the absorption of spectra obtained from these samples at given wavelengths can be directly related to the sample concentration. Normally, UV and UV-visible spectra are recorded at high and low pH, and the results of both are compared …
